I recommend to use AP U.S history crash course
The Good:
This book is helpful when getting into some last minute studying. It is not geared towards giving you a comprehensive view of AP US History. Instead, it specifically focuses on the tips for being successful with the test. A “crash course” is just the right description for this book. It helps you avoid getting caught up in the monotony of facts and information that won’t actually be on the test.
The makers of this book have analyzed the newest version of the APUSH course and exam outline to give you just the information you need. Besides that, it includes some pretty helpful test-taking tips and strategies. It will help you think about how to approach both the multiple-choice sections and the essay portions.
One of the unique features included in this review book is the online practice exam. This exam features instant feedback as well as an explanation of answers. Having self-assessment helps you see how much further you have to go before you are really prepared for the APUSH exam. These practice tests can really serve as a guide for the rest of your studying.
The Bad:
This book is a trimmed down version of the AP US History course. That means it does not cover all of the details you could learn in class or read in other books. It is a review book without any fluff, which can make it harder to find general overview information about themes and big ideas. Even with these issues in mind, this is still one of the best APUSH review books out there.
Beacuse we're suppose to work it out and see if it is right or wrong.
It's really an opinion question from your perspective of terrorism.
The correct answer is Neutron
Explanation:
As shown in the diagram the sub-particles in atoms are electrons, neutrons, and protons. From these, the two types of particles that are in the nucleus or center of the atom are neutrons and protons. Moreover, neutrons differ from protons because these are neutral or are not charged. According to this, the uncharged particles in atoms are neutrons.
Moreover, the number of neutrons can be calculated by subtracting the atomic number (number of protons) to the mass number (number of atoms and protons). For example, if in an atom the mass number is 12 (protons and neutrons)and the atomic number is 6 (number of protons), the neutrons are 6 (12 - 6 = 6). According to this, the correct answer is the neutron.
